StarCraft custom map called We Are Friend. It was kind of an anime spellcasting brawler sort of map, very intricate and high skill, a progenitor to the arena battle games that would later become the MOBA genre.
It had Archer EMIYA and Gilgamesh as selectable characters, throwing swords at other people in various ways. The bottom left corner of the map was Unlimited Blade Works, a place EMIYA could drag other players into to massacre them. Very fun. Old memories.
